Superwholock (+reader) (part 3)

“Welcome, Winchesters, Holmes, Watson, Doctor and (L/N).” A masculine voice said in a seductive tone.
Dean reached towards his waist, as if to take out a gun, then stopped. “We’ve got no weapons,” he muttered, hatred dripping from his voice.
“And you’re stuck here, Dean-o!” Suddenly, everyone, well, the Winchesters and (Y/N) froze. “Gabriel?” “In the flesh, er, in the vessel.”
“Why’d you bring us here, Gabriel?” Sam asked calmly. Heat of the Moment began to play in the background. Just kidding. But it did start to play from a speaker on the wall.
The archangel rolled his eyes. “Kiddo, it wasn’t me.”
“Wasn’t you, huh?” (Y/N) hissed. “Then why did you just appear?”
The Doctor frowned. “We’ve got another guest,” he said, gesturing at another male figure lying across the floor. John rushed forward.
The doctor, well, John’s forehead creased. “I’m sorry Doctor, I think he’s dead.”
“Give it a minute…”
Jack Harkness inhaled sharply. “Hey, Doctor.” He grinned, sitting up. “You okay?”
John seemed to hyperventilating. “How the hell…?”
“I’m immortal, name’s Captain Jack Harkness. And you are?”
“John Watson.”
“There’s a time and a place, Jack.”
“I was only saying hello!”
“For you, that’s flirting.”
Somehow, in that short time, Gabriel had managed to climb onto Sam’s shoulders and ride him, yelling “Giddyup, Moose!”
Sam sighed, and deposited the archangel on the floor. “Sorry, some other time.”
For some reason, people were joining this small party, and it probably wasn’t good that all the heroes in the universe were in danger.
And Sherlock intended to find out why.
